firefox vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in Firefox.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

Christoph Diehl, Christian Holler, Mats Palmgren, Chiaki Ishikawa, Bill
Gianopoulos, Benoit Jacob, Gary Kwong, Robert O'Callahan, Jesse Ruderman,
and Julian Seward discovered multiple memory safety issues affecting
Firefox. If the user were tricked into opening a specially crafted page, an
attacker could possibly exploit these to cause a denial of service via
application crash, or potentially execute code with the privileges of the
user invoking Firefox. (CVE-2013-0769, CVE-2013-0749, CVE-2013-0770)

Abhishek Arya discovered several user-after-free and buffer overflows in
Firefox. An attacker could exploit these to cause a denial of service via
application crash, or potentially execute code with the privileges of the
user invoking Firefox. (CVE-2013-0760, CVE-2013-0761, CVE-2013-0762,
CVE-2013-0763, CVE-2013-0766, CVE-2013-0767, CVE-2013-0771, CVE-2012-5829)

A stack buffer was discovered in Firefox. If the user were tricked into
opening a specially crafted page, an attacker could possibly exploit this
to cause a denial of service via application crash, or potentially execute
code with the privileges of the user invoking Firefox. (CVE-2013-0768)

Masato Kinugawa discovered that Firefox did not always properly display URL
values in the address bar. A remote attacker could exploit this to conduct
URL spoofing and phishing attacks. (CVE-2013-0759)

Atte Kettunen discovered that Firefox did not properly handle HTML tables
with a large number of columns and column groups. If the user were tricked
into opening a specially crafted page, an attacker could exploit this to
cause a denial of service via application crash, or potentially execute
code with the privileges of the user invoking Firefox. (CVE-2013-0744)

Jerry Baker discovered that Firefox did not always properly handle
threading when performing downloads over SSL connections. An attacker could
exploit this to cause a denial of service via application crash.
(CVE-2013-0764)

Olli Pettay and Boris Zbarsky discovered flaws in the Javacript engine of
Firefox. An attacker could cause a denial of service via application crash,
or potentially execute code with the privileges of the user invoking
Firefox. (CVE-2013-0745, CVE-2013-0746)

Jesse Ruderman discovered a flaw in the way Firefox handled plugins.  If a
user were tricked into opening a specially crafted page, a remote attacker
could exploit this to bypass security protections to conduct clickjacking
attacks. (CVE-2013-0747)

Jesse Ruderman discovered an information leak in Firefox. An attacker could
exploit this to reveal memory address layout which could help in bypassing
ASLR protections. (CVE-2013-0748)

An integer overflow was discovered in the Javascript engine, leading to a
heap-based buffer overflow. If the user were tricked into opening a
specially crafted page, an attacker could possibly exploit this to execute
code with the privileges of the user invoking Firefox. (CVE-2013-0750)

Sviatoslav Chagaev discovered that Firefox did not properly handle XBL
files with multiple XML bindings with SVG content. An attacker could cause
a denial of service via application crash, or potentially execute code with
the privileges of the user invoking Firefox. (CVE-2013-0752)

Mariusz Mlynski discovered two flaws to gain access to privileged chrome
functions. An attacker could possibly exploit this to execute code with the
privileges of the user invoking Firefox. (CVE-2013-0757, CVE-2013-0758)

Several use-after-free issues were discovered in Firefox. If the user were
tricked into opening a specially crafted page, an attacker could possibly
exploit this to execute code with the privileges of the user invoking
Firefox. (CVE-2013-0753, CVE-2013-0754, CVE-2013-0755, CVE-2013-0756)

Two intermediate CA certificates were mis-issued by the TURKTRUST
certificate authority. If a remote attacker were able to perform a
man-in-the-middle attack, this flaw could be exploited to view sensitive
information. (CVE-2013-0743)

Update instructions:
